Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14ÏÏ”0. d)the ball will oscillate along the z axis between z=d and z=âd in simple harmonic motion. what will be the angular frequency Ï of these oscillations? use the approximation dâȘa to simplify your calculation; that is, assume that d2+a2âa2. express your answer in terms of given charges, dimensions, and constants
